The rest of the world is not pleased with the president-elect’s climate change denialism and will make us pay.

Nicolas Sarkozy proposed a carbon tax on American-made goods if President-elect Donald Trump pulls out of the climate accord.

On Sunday, Sarkozy told the French television channel TF1 that he would “demand that Europe put in place a carbon tax … of 1 to 3 percent for all products coming from the United States, if the United States doesn’t apply environmental rules that we are imposing on our companies.”

Sarkozy served as the French head of state from 2007 to 2012 and is currently running for office again.

While there is a four-year waiting period to formally pull out of the Paris accord, Trump can refuse to adhere to President Obama’s pledge to cut emissions to 26 percent below 2005 levels by 2025, as well as decline to contribute to global climate funds or attend United Nations climate meetings.
